ToaZZ 107mm 'it may concern Be it known that l, CURTIS R. MA'r'rnnN,

a citizen ot the United States, residing at Tower City, in the county ofSchuylkill and State ot Pennsylvania, have invented new and usefulCement-Bag Cleaner, of which the following is a specification. Y

This invention aims to provide novel means whereby cement bags and otherartieles may be cleaned, novel means being provided for holding` thebags, and novel means being' provided :tor directing a blast o1 airunder pressure through the bags.

1t is within the province of the disclosure te improve generally andv toenhance the utility ot oevices of that type to which the inventionappertains. n

lVith the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement ot parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes inthe preciseembodiment ot the invention herein disclosed, may be made within thescope of what is claimed, Without departing from the spirit oi theinvention.

ln the drawings Y Figure 1 shows in side elevation, a device constructedin accordance withv the invention; Figure 2 is a top plan wherein partsare broken away; Figure 3 is a vertical longitudinal section; Figure ais a cross section on the line l1l1 ot Figure 3; remote parts beingomitted.

The machine forming the subject matter of this application includes acasing 1 supported at one end on long legs 2, and at its opposite end onshort legs 3. rlthe casing 1 comprises a bottom l having a downwardlyinclined end 5, an end wall 6, a curved or convened top member 7, aconcaved .top member 8 located above the end 5 ot the bottom 4, andsides 9. A lid 10 is hinged to one end of the top member 7 and is heldclosed with respect to the end wall 6 by means of a latch 12, the hingefor the lid 10 being marked by the numeral 11` The lid 10 has a handle1-1 whereby it may be manipulated readily. A conveXed lid 15 is hingedat 16 to the upper end of the top member 8 and cooperates with the topmember 7. Near to its free end, the lid 15 has Serial N0. 56,029.

an upstanding loop-shaped handle 17 provided w l lateral extensions 1Sprolonged beyond the sides 9 and adapted to be'engaged by latches 19pivoted at 2() to the sides 9 for vertical swinging movement. The bottoml is wherein a valve27, under the control of an operator, is interposed,the air conduit A26 having horizontally spaced branches 28 pass ingthrough the end wall 6 in close circulation to 'the bottom 11 andadapted to discharge air under pressure into the feed chamber 24.

ln practical operation, the lid 10 is opened, and the cement led in bagsis introduced prolonged to form a grating 21, which may be a perioratedconcave.

under the blast et air, the air depriving the bags of the cement andother foreign material, the cement and foreign material being blown`through the perforated concave 21 and leaving the machine by way ot theout'- let spout 25. -After the bags have been cleaned sufficiently, theymay be `removed from the drum 23 by opening the top lid 15.

rlhe air under pressure which yis discharged through the branches 28 ofthe conduit 26, moves Vin approximate parallelism .with the bottommember 4l, toward the screen or conca-ve 21. The air not only is blownthrough the bags, but the bags, as well, are caused to move in an orbitaround the circle formed in part by the screen 21, the lid 15 and theconvened top member 7.
